We determine an asset’s condition development to determine its remaining useful life in specific usage conditions. At the basis of this, is thorough knowledge of materials behavior in many different circumstances. This enables us to assess the degradation mechanisms of specific materials, materials combinations and structures. Knowledge of the degradation mechanisms is crucial in knowing what tests or measurements to perform, and how.
Using this knowledge, our experts can build up a detailed picture of the condition (degree of degradation) of your equipment. They achieve this by carrying out a number of tests and measurements. The aspects we consider include:
- the extent and cause of degradation (including cracks or crack initiation, wear, corrosion and ageing);
- the condition of the material; and
- the loads a component or construction must be able to withstand. For example, heat or moisture.
We use various measurement and research techniques and calculations to identify any degradation of a piece of equipment or component. This enables us to develop models that accurately show the tolerance of the material in question. In other words: what it will be able to withstand before it stops functioning properly. We establish the preventive measures necessary in consultation with you and on the basis of the results obtained. For example, the replacement of parts in a system, or changes outside the system itself, to reduce the load on the system. The object of preventive measures will always be to extend the remaining lifetime of components.
Remaining lifetime determination by DEKRA
We draw on our expertise and years of experience to establish the best way for us to help you. Our experts are up to date with the most relevant standards and requirements for components.
DEKRA’s experts will take their investigation results and prepare a report for you. It will set out the expected remaining lifetime per component, including the margin of uncertainty and any measures that could extend the lifetime of components, and facilitate optimised asset management. You will sometimes need the information in the report to comply with legislation or regulations. DEKRA can also put together a component reconditioning framework for you if you would like it to.
We will work with you and consider your specific situation at all times so that you benefit from a tailor-made investigation. We will communicate effectively with you in every phase of our investigation as well so that you understand our approach and we are able to align our investigation to your particular needs as much as possible.
Examples from the field
DEKRA has worked on unique cases for a very wide range of different parties. To give just two examples: we work with several clients to determine the remaining lifetime of steel-rubber parts in bogies. Our investigation results enabled one of these clients to reduce the number of overhauls necessary by one during the concession period. For another client, we investigated the lubricants used in the gearboxes of trains. This particular client is now able to avoid unexpected failures and extend its overhaul periods.
Why DEKRA?
DEKRA is an expert in asset lifecycle management and can test your materials, parts and components for you. DEKRA has been determining and extending the remaining lifetime of clients’ assets in the Netherlands for more than 60 years now. We have been continually improving our methods as well - which we always do in close consultation with clients.
Our experts deliver a tailor-made approach and investigation. We use the advanced equipment in our well-equipped laboratories to test and measure your components, systems and materials and arrive at substantiated advice, measures and solutions.
